STEAM-SEPARATOR.

To all whom it may concern:

Be it known that 1', CARL O. NEWBURGH, a citizen of the United States,residing at Rockford, in the countyof Winnebago and State of Illinois,have invented certain new and useful Improvements in Steam-Separators,of which the following is a specification. This invention pertainstosteam separators adapted to be interposed in steam pipe lines forremoving grease, dirt, water and other foreign matter from the steam soas to render it clean and dry. Under certain working conditions thesteam is quite heavily laden with foreign matter and the object ofclarifying this steam without appreciably lowering its pressure isdifficult to attain because of the peculiar conditions present. Suchworking condition vis'especially present when low pressure or exhauststeam from steam hammers, presses, etc, is used for operating turbines.1 The exhaust steam carries an unusually large percentage of grease,grit, etc, which if not entirely separated from the steam, will sooneror later seriously wear, clog and injure-the thus necessitating frequentdismantling,

on the market are very ineflicient under the conditionsment oned as theynot only fail to entirely separate the foreign matter from the steam,but they impose such an obstruceign matter from the steam withoutlowering the pressure.

I have also aimed to provide a'steam separator of such simple design andconstruction asto warrant its production at a comparatively low cost.

:A' further object is to provide "a steam forcleaning purposes, forintime certain particles will accumulate and adhere tothe separatorelement instead of being drained or carried away with the bulk offoreign or reservoir. In the present element Specification of LettersPatent.

moved as an entirety and the accumulation burned off very quickly.

Other objects and attendant advantages will be appreciated as theinvention becomes better understood by reference to the followingdescription when considered in connection with the accompanyingdrawings, in which- I Y V Figure 1 is a vertical sectional view througha steam separator embodying my mprovements, showing the separatorelements in elevation; and

2 is a plan sectional view taken on the l1ne-22 of Fig.- 1.

' My improved steam separatorlis adapted to beinterposed in any steampipe line in oil,

as'mentione'd above, it isparticularly serviceable and eflicient underthe most severe conditions. That 1s, 1n the case of low pressure exhauststeam taken from steam presses,

hammers, etc., where an unusually large amount of oil, dirt and otherforeign matter is gathered'by the steam, my improved separator willthoroughly remove this foreign matter from the steam, and in such awa'y'as not to lower the steampressure.

In the present illustrationof my improvement, the steam pipe lineincludes sections 4, 5, 6 and 7. This is intended to exemplify a sectionof any steam line. In the particular illustration mentioned, the pipesection 4 leads from the source of exhaust steam, and the steam afterhaying been clarified'is ideliyere'd' th ough the section 7 to the pointhammersfpresses or other of usage, as 'to a steam turbine; The section5, which'incloses the separator is preferably. flanged at its ends andbolted between the adj oinin' pipe sections so as to be readily -removabeand also to provide a straight uninterrupted passage for the steam. .7Centrally within the pipe section 5 is rigidly but jdetachably mounted atubular, body 8, allowing a circumferential steam passage 9 through saidipe section. This tubular'body held inthe desired position by anysuitable means, and in the present case is so held by upper and lowerrods 11 eX'tendingdiametrically through and rigidly secured to thetubular body and seated attheir ends in sockets 12 in plugs 13esreaaingly engaged ma be in the pipe section 5. When the section 5 isremoved from the pipe line the tubular member 8 may be removedlengthwiserby loosening the ,plugs 13, as Willheobvious.

The tubular member 8" constitutes a central) conduit closed at its end14 and open at its end 15 and adapted to receive'fore 'gn rnah duitWithout lowering 'the steam pressure.

These separator -blades may be of suitable construction and .arepreferably arranged radially in the passage 9 and spaced c1rc-umferentially around the central me1 nber 8 1n spiral rows, as clearlyillustrated 1n.'F1g. 1. Each bladehas an open face in the path of thes'team*and' a channel leading into the central conduit. Theforeignmiatterintercepted by these faces will "be guided'through thechannels into'the central conduit, thence I conveyed to an outlet. Asimple and effecan form of blade is that shown, consisting of pipesections 16 secured'in an opening thronghfthe tubular memberv andextending radially therefrom and inclined toward the incoming steam. Theupper face of each radial pipe. is cut away,thus leaving an openchannell'eading' into the'centra'l conduit. As

shownryclearly in F ig. 2, --the se open face channels of the separatorblades intercept blades ata relativelyfhig'h or 'steep pitch, the steam.Las it passes through the passage 9 will not be obstructed to theextent oflovvering its 1 pressure. ,The. steam body Will sub-.stantially; follow thespiral path of the 'lblades,.andri n so doingtheforeign particles Willat sometime infltheir passage through .thisiblade arcabeintercepted by thebl ades and carried into Ithefcent'ralconduit.
